Abstract: An integrated circuit device comprising a power control unit for controlling the power of a power isle is disclosed. The power control unit comprises (i) a power gating switch implemented in the BEOL portion for switching ON/OFF the power to the power isle, (ii) a state recovery circuit comprising a memory element in the FEOL portion or BEOL portion and a transistor configuration in the BEOL portion, and (iii) a wake-up/sleep circuit in the BEOL portion adapted for receiving an identifier. The wake-up/sleep circuit is operatively connected with the power gating switch and with the state recovery circuit. Responsive to receiving the identifier, the wake-up/sleep circuit causes the power gating switch to switch OFF/ON the supply power to the power isle and causes the state recovery circuit to store/restore the state of the power isle.
